Which of the following options BEST explains the pesticide paradox principle of testing?

Testing, like spraying pesticide, is an effective bug/defect removal activity.

Defects are, paradoxically, often contained in a small number of modules.

Repeatedly running a set of tests will ensure that a system is defect free.

If we do not regularly review and revise our tests, we'll stop finding defects.

Component and Component integration test levels only.

All test levels.

After a record of poor quality software releases (incorrect menu selection options, new features that do not work, users allowed to change security levels without administrator rights), you have been asked to review the test capability in your company. You have limited time to do the review before the next project, which type of testing would be MOST appropriate to review first?

Functional testing.

Non-functional testing.

Performance testing.

White-box (structural) testing.
